Only 30km from Northern Star’s Paulsens gold mine is our Mt-Clement project - with a JORC Resource of 64,400oz gold and 618,500oz silver.

 

The Mt Clement tenements are 30 km southwest of the Northern Star Resources Ltd (ASX: NST) Paulsens gold mine and plant. Northern Star has entered into a JV on this project with Artemis maintaining an 80% interest as project operators.

Geology and mineralisation

The main prospect at Mount Clement lies within a lens of oxidized and silicified siliciclastic and chemical rocks which are generally conformably confined within the Ashburton Formation. The lower part of the lens (LMZ) contains anomalous levels of silver, arsenic and gold. The upper part of the lens (UBZ) is extensively silicified and ferruginised and characterised by anomalous manganese.

The Main prospect is interpreted by Davy et al (1991) as a sediment-hosted, deep-marine, hot-spring deposit.

The Eastern prospect at Mount Clement is a sulphide bearing fracture filling formed as a result of dextral wrenching after the deposition of the Ashburton Formation. It is characterised by anomalous levels of silver, arsenic and gold which may have been derived, in part by leaching of wall rocks.

Metal-bearing fluids were probably released during burial metamorphism of the supracrustal sequence, and subsequently transported along major fractures. These fractures were either formed, or reactivated, during continental crustal collision between the Pilbara and Yilgarn Cratons.

 

Mineral Resources

Artemis commissioned Apex Geoscience (Apex) in July 2011 to complete a mineral resource estimate for the Mt Clement Project. This resource estimate, was reported in accordance with the 2004 JORC Code  and utilised all existing data including a total of 90 RC and diamond drill holes.

Apex estimated an Inferred Resource at a lower cut-off grade of 0.5 g/t Au of approximately 1.1 Mt @ 1.77 g/t Au and 17.0 g/t Ag for a contained 64,400 oz Au and 618,500 oz Ag. The mineralisation remains open at depth and along strike, indicating strong potential to substantially increase these resources with further drilling. Artemis plan further work at Mt Clement including upgrading of the resource estimate so that it  can be reported in accordance with the 2012 JORC Code.

Nagrom’s LeachWELL bottle roll tests in February 2017 with gold recoveries at over 97% confirms that the Mt Clement project mineralisation is amenable to conventional cyanide leaching.  A scoping study, managed and co-funded by Blackrock Metals Pty Ltd, will determine the feasibility of open pit mining and heap leaching of the gold

Outside of our key area near Karratha, these tenements are in the Shire of Ashburton, between Paraburdoo and the Nanutarra Roadhouse.

Northern Star Resources Ltd (ASX: NST) has been one of this decade’s success stories for gold. Their Paulsens gold mine and plant are only 30km north of our Mt Clement tenements.

In fact, we have joint ventured with Northern Star for this project – and we maintain an 80% interest as project operators.
